Far Cry 3 Blood Dragon Classic Edition

EDIT: This keeps getting downvoted but without comment. If something is flawed in my solution, please leave a comment and I will fix it.

There are a total of twelve different animals to kill:

Robo-Crocs
Mutant Buffalo
Devil Goat
Mutated Cassowary
Mutated Turtles
Robo Dog
Blood Dragon
Cyber-Shark
Cyber-Panther
Neon Snakes
Boar
Black & White Tiger

Most of these are pretty straightforward and the map is marked with territories more likely to have them. The exceptions are:

Blood Dragons (random, but everywhere). Killing one will not only give you progress on this achievement, but will also pop the Blood Dragon Down achievement for killing your first one. And, if you weaken it first and then use the bow to finish it off, you’ll also net the “Just the Tip” achievement. You can lure nearby Dragons with hearts torn from dead enemies that you pilfer.

Neon Snakes (found mostly in low grass; they’ll attack and do mild damage, and you’ll have a few seconds to kill them before they slither away).

And Mutated Turtles, which can only be found in a Predator Path mission. There are four familiar turtles to kill; you’ll have to use your knife.

You can check your progress in the main menu under Data Console - Animals

Good hunting!

In addition to the animal types you see on the map, there are 5 types you need to kill that are not seen - Mutated Turtle - Predator mission
Robo-Croc - found in some areas underwater and there is one in the turtle Predator mission.
Robo-Dog - found in story progression.
Neon Snake - I found this one after the story mission when you are searching for Dr. Carlyle, near the building with the hang glider.
Blood Dragon - easy to find in normal play, you will kill at least one in story progression.

Complete all of the Predator missions and you will get most of the kills needed. The snake was the last one for me, and I found it in story progression, but I imagine it can be easily missed.
